Answers: Human Evolution

Q6. Outline one way that advances in medicine and/ or in technology have or can contribute to human evolution
  • Reproductive technology allows the prediction of the likelihood of inherited a genetic disease by prenatal testing. This can enable parents to choose not to have a particular offspring, affecting the gene pool
  • In vitro fertilization has enabled couples who would normally not breed to have children
  • Stem cell manipulation has allowed research into differentiating stem cells so that such cells can be transplanted into people who need cells such as brain cells
  • Medical treatment of people carrying a genetic defect such as haemophilia enabling them to possibly breed could increase the incidence of genetic diseases in the community
